Abstract

PURPOSE: To remarkably improve the cutting property of alloy, by containing Al and O2 in hard phase mainly composed of Ti and sintered hard alloy composed of iron group metal etc. as combination metal.
CONSTITUTION: Hard phase containing 20W50 mol % of Ti, composed of carbide, nitride and oxide of each group metal of IVa, Va, VIa as the rest and hard alloy sintered by comination metal of iron metal group, substituted 0.2W25wt.% of the iron metal group by more than one kind of Cu, Ag, Si, B, are manufactured. On occasion of showing the composition of the hard phase as M(Cu NvOw)z, M is metal constituent, such as Ti etc. and the quantity of C,N,O2 is shown as follows; 0.49≤u≤0.95, 0.04≤v≤0.36, 0.01≤w≤2.0, 0.80≤z≤1.05. Solid solution is formed by adding Al with O2 in hard phase and bonding layer within the limits of 0.1W 20wt.% or at the same time, each group metal of IVa, Va, VIa, C, N, O2 and Al, are dispersed in the form of compound. Abrasion resisting property, thermal toughness, cutting property, are improved remarkably.
